Darüber betrifft die Erfindung einen Akkumulator zur Durchführung des Verfahrens, wobei der Akkumulator eine erste Datenschnittstelle sowie einen Aufweckschaltkreis enthält zum Aktivieren einer Steuerungselektronik des Akkumulators.In addition, the invention relates to an accumulator for carrying out the method, the accumulator containing a first data interface and a wake-up circuit for activating control electronics of the accumulator.

Kabellose Werkzeugmaschine können zur Strom- bzw. Energieversorgung mit einem Akkumulator, auch Akku genannt, betrieben werden. Hierzu wird der Akkumulator über eine entsprechende Schnittstelle mit der Werkzeugmaschine so verbunden, dass elektrischer Strom von dem Akkumulator zur Werkzeugmaschine fließen kann. Bei der kabellosen Werkzeugmaschine kann es sich beispielsweise um einen Akku-Schrauber, einen Bohrhammer oder dergleichen handeln.Cordless machine tools can be operated with an accumulator, also known as a rechargeable battery, to supply electricity or energy. For this purpose, the accumulator is connected to the machine tool via a corresponding interface in such a way that electric current can flow from the accumulator to the machine tool.

Auf dem Markt befindliche Akkumulatoren enthalten für gewöhnlich eine Anzahl an Speicherzellen bzw. Energiespeicherzellen für elektrische Energie bzw. für eine elektrische Spannung. Zur Kontrolle eines Lade- bzw. Entladevorgangs der Energiespeicherzellen, bei dem die Energiespeicherzellen entweder mit einer elektrischen Energie geladen oder die elektrischeAccumulators on the market usually contain a number of storage cells or energy storage cells for electrical energy or for an electrical voltage. To control a charging or discharging of the energy storage cells, in which the Energy storage cells are either loaded with electrical energy or the electrical

Energie aus den Speicherzellen genommen (entladen) wird, verfügt ein moderner Akkumulator über eine Steuerungselektronik zur Regelung und Steuerung verschiedener Vorgänge in dem Akkumulator. Die Speicherzellen werden auch als Akku-Zellen oder Sekundärzellen bezeichnet. Um elektrische Energie eines Akkumulators zu sparen wird die Steuerungselektronik des Akkumulators in einen Deaktivierungsmodus (auch als Schlafmodus bzw. Schlafzustand bezeichnet) versetzt, wenn die akkubetriebene Werkzeugmaschine für eine gewisse Zeitdauer nicht betrieben wird. In diesem Deaktivierungsmodus fließt kein elektrischer Strom von dem Akkumulator in die Steuerelektronik und/oder zu der Werkzeugmaschine.If energy is taken from the storage cells (discharged), a modern accumulator has control electronics for regulating and controlling various processes in the accumulator. The storage cells are also referred to as battery cells or secondary cells. In order to save electrical energy in an accumulator, the control electronics of the accumulator are put into a deactivation mode (also referred to as sleep mode or sleep state) if the battery-powered machine tool is not operated for a certain period of time. In this deactivation mode, no electric current flows from the accumulator into the control electronics and/or to the machine tool.

Wenn jedoch die akkubetriebene Werkzeugmaschine wieder in Betrieb genommen werden soll, damit erneut elektrischer Strom von dem Akkumulator zu den elektrischen Verbrauchern der Werkzeugmaschine fließen kann, muss der Akkumulator zunächst reaktiviert, d.h. von dem Deaktivierungsmodus in einen Aktivierungsmodus (d.h. aufgeweckt) versetzt werden. Der Akkumulator muss sich im Aktivierungsmodus befinden, um beispielsweise die Strommenge bzw. die Stromstärke zu steuern, die zu der Werkzeugmaschine fließt, oder die Temperatur des Akkumulators zu überwachen.However, if the battery-operated machine tool is to be put back into operation so that electric current can flow again from the accumulator to the electrical consumers of the machine tool, the accumulator must first be reactivated, i.e. switched from the deactivation mode to an activation mode (i.e. woken up). The accumulator must be in the activation mode in order, for example, to control the amount of current flowing to the machine tool or to monitor the temperature of the accumulator.

Eine derartige Reaktivierung des Akkumulators stellt jedoch einen gewissen Aufwand dar, da mit Hilfe eines gesonderten Signals in Form eines Spannungsimpulses zunächst ein Aufweckschaltkreis des Akkumulators aktiviert werden muss. Der Aufweckschaltkreis (re-)aktiviert anschließend die Steuerungselektronik des Akkumulators, damit die Versorgung der Werkzeugmaschine mit elektrischem Strom fortgesetzt werden kann.Such a reactivation of the accumulator, however, represents a certain amount of effort since a wake-up circuit of the accumulator must first be activated with the aid of a separate signal in the form of a voltage pulse. The wake-up circuit then (re-)activates the control electronics of the accumulator so that the power supply to the machine tool can continue.

Akkumulatoren gemäß dem Stand der Technik bieten zur Lösung dieses Problems eine separate Leitung von der Steuerung der Werkzeugmaschine zum Aufweckschaltkreis des Akkumulators an. Die Bereitstellung einer derartigen Leitung ist jedoch aufwendig und erzeugt zusätzliche Kosten sowie Platzprobleme. DE 10 2015 010739 A1 offenbart ein Verfahren zur Steuerung eines Akkumulators an einer Werkzeugmaschine aus dem Stand der Technik.Prior art accumulators offer a separate line from the machine tool controller to the accumulator wake-up circuit to solve this problem.

Hierdurch kann auf einfache Art und Weise erreicht werden, dass der Aufweckschaltkreis des Akkumulators mit Hilfe der differentiellen Kommunikation ein entsprechendes Signal in Form eines Stromimpulses detektiert, um die Steuerungselektronik des Akkumulators zu reaktivieren. Die dargestellte Lösung ist sowohl platz- als auch kostensparend, da ein bereits vorhandenes Kommunikationssystem verwendet werden kann.This makes it possible in a simple manner for the wake-up circuit of the accumulator to detect a corresponding signal in the form of a current pulse with the aid of differential communication, in order to reactivate the control electronics of the accumulator. The solution presented saves both space and money, since an existing communication system can be used.

Die erste und zweite Kommunikationsleitung für eine differentielle Kommunikation zwischen dem Akkumulator und der Werkzeugmaschine sind Bestandteile eines Kommunikationssystems. Das Kommunikationssystem kann dabei als CAN-Datenbus ausgestaltet sein. Es ist jedoch auch möglich, dass ein anderes geeignetes Kommunikationssystem für eine differentielle Kommunikation zwischen dem Akkumulator und der Werkzeugmaschine verwendet wird.The first and second communication lines for differential communication between the accumulator and the machine tool are components of a communication system. The communication system can be designed as a CAN data bus. However, it is also possible for another suitable communication system to be used for differential communication between the accumulator and the machine tool.

Die Freigabe einer Stromentnahme von dem Akkumulator durch die Werkzeugmaschine bedeutet, dass die Werkzeugmaschine mit Hilfe einer Strommesseinrichtung in der Lage ist, den Strom, der von dem Akkumulator zur Versorgung der Werkzeugmaschine bereitgestellt wird, zu messen und eine maximal mögliche Strommenge bzw. ein Versorgungsstrom mit einer maximal möglichen Stromstärke von dem Akkumulator zu der Werkzeugmaschine fließen zu lassen. Hierzu wird der Akkumulator durch die Werkzeugmaschine so eingestellt, dass nur ein maximal möglicher Versorgungsstrom zu der Werkzeugmaschine gelangen kann.The release of a current draw from the accumulator by the machine tool means that the machine tool is able to use a current measuring device to measure the current that is provided by the accumulator to supply the machine tool measure and allow a maximum possible amount of current or a supply current with a maximum possible current intensity to flow from the accumulator to the machine tool. For this purpose, the accumulator is set by the machine tool in such a way that only a maximum possible supply current can reach the machine tool.

Die Aufgabe wird des Weiteren gelöst durch ein System enthaltend einen Akkumulator und eine Werkzeugmaschine zur Durchführung des Verfahrens, wobei der Akkumulator eine erste Datenschnittstelle sowie einen Aufweckschaltkreis enthält zum Aktivieren einer Steuerungselektronik des Akkumulators und die Werkzeugmaschine eine zweite Datenschnittstelle sowie eine Steuerung enthält, und wobei die Datenschnittstellen über eine erste und zweite Kommunikationsleitung für eine differentielle Kommunikation zwischen dem Akkumulator und der Werkzeugmaschine miteinander verbunden sind.The object is also achieved by a system containing an accumulator and a machine tool for carrying out the method, the accumulator containing a first data interface and a wake-up circuit for activating control electronics of the accumulator and the machine tool containing a second data interface and a controller, and wherein the Data interfaces are connected to one another via a first and second communication line for differential communication between the accumulator and the machine tool.

In Figur 1 ist ein erfindungsgemäßes System 1 mit einer Werkzeugmaschine 2 und einem Akkumulator 3 dargestellt. Der Akkumulator 3 ist mit der Werkzeugmaschine verbunden und dient zur Versorgung der elektrischen Verbraucher der Werkzeugmaschine 2 mit elektrischer Energie. Bei der Versorgung fließt elektrischer Strom von dem Akkumulator 3 zu der Werkzeugmaschine 2.In figure 1 a system 1 according to the invention with a machine tool 2 and an accumulator 3 is shown. The accumulator 3 is connected to the machine tool and is used to supply the electrical consumers of the machine tool 2 with electrical energy. During the supply, electric current flows from the accumulator 3 to the machine tool 2.

Wie in Figur 1 dargestellt, ist die Werkzeugmaschine 2 in Form eines Akku-Schraubers dargestellt. Gemäß anderer alternativer Ausführungsformen kann die Werkzeugmaschine 2 auch in Form einer Bohrmaschine, einer Säge oder dergleichen ausgestaltet sein.As in figure 1 shown, the machine tool 2 is shown in the form of a cordless screwdriver.

Die Abtriebswelle 12 überträgt das Drehmoment auf das Getriebe 10, welches wiederum ein Drehmoment an die Antriebswelle 11 weitergibt. Über die Antriebswelle 11 wird durch Übertragung des Drehmoments die Werkzeugaufnahme 7 angetrieben. Wie in Figur 1 dargestellt, ist in der Werkzeugaufnahme 7 ein Werkzeug 14 in Form eines Bits gehalten. Mit Hilfe des Bits kann eine Schraube in einen Werkstoff eingeschraubt werden. Weder die Schraube noch der Werkstoff sind in den Figuren dargestellt.The electric drive 8 configured as an electric motor, the gear 10 , the drive shaft 11 , the output shaft 12 and the control 9 are positioned in the housing 4 . The drive 8, the transmission 10, the drive shaft 11 and the output shaft 12 are positioned relative to one another and in the housing 10 such that a torque generated by the drive 8 is transmitted to the output shaft 12. The output shaft 12 transmits the torque to the transmission 10, which in turn transmits torque to the drive shaft 11. The tool holder 7 is driven via the drive shaft 11 by transmission of the torque. As in figure 1 shown, a tool 14 in the form of a bit is held in the tool holder 7 . A screw can be screwed into a material with the help of the bit. Neither the screw nor the material are shown in the figures.

Wie weiterhin in Figur 1 gezeigt, enthält das Gehäuse 4 eine Oberseite 4a und eine Unterseite 4b. Der Handgriff 5 enthält ein erstes Ende 5a und ein zweites Ende 5b. An der Unterseite 4b des Gehäuses 4 ist das erste Ende 5a des Handgriffs 5 befestigt. Des Weiteren enthält das Fussteil 6 ein oberes Ende 6a und ein unteres Ende 6b. Das obere Ende 6a des Fussteils 6 ist an dem zweiten Ende 5b des Handgriffs 5 befestigt. Das untere Ende 6b des Fussteils 6 enthält eine mechanische, elektrische und elektronische Schnittstelle 15 und dient zum mechanischen, elektrischen und elektronischen Verbinden mit dem Akkumulator 3. Zur Aufnahme von elektrischen Strom enthält die Schnittstelle 15 eine Anzahl an Stromanschlüssen 16. Die Schnittstelle 15 enthält darüber hinaus Datenanschlüsse 17 zum Senden und Empfangen von Signalen zwischen der Werkzeugmaschine 2 und dem Akkumulator 3.As continues in figure 1 As shown, the housing 4 includes a top 4a and a bottom 4b. The handle 5 includes a first end 5a and a second end 5b. On the underside 4b of the housing 4, the first end 5a of the handle 5 is attached. Furthermore, the foot part 6 includes an upper end 6a and a lower end 6b. The upper end 6a of the foot part 6 is attached to the second end 5b of the handle 5 . The lower end 6b of the foot part 6 contains a mechanical, electrical and electronic interface 15 and is used for mechanical, electrical and electronic connection to the accumulator 3. The interface 15 contains a number of power connections 16 for receiving electrical current. The interface 15 contains above addition, data connections 17 for sending and receiving signals between the machine tool 2 and the accumulator 3.

Wie den Figuren 1 und 2 zu entnehmen ist, ist die Steuerung 9 der Werkzeugmaschine 2 in dem Fussteil 6 der Werkzeugmaschine 2 positioniert. Die Steuerung 9 der Werkzeugmaschine 2 dient zum Steuern und Regeln verschiedener Vorgänge in Bezug auf die Werkzeugmaschine 2 sowie in Bezug auf den Akkumulator 3. Die Steuerung 9 steuert insbesondere den Strom bzw. die Stromstärke, die von dem Akkumulator 3 zu der Werkzeugmaschine 2 und insbesondere zum Antreiben des als Elektromotor ausgebildeten Antriebs 8 fließt.Like the figures 1 and 2 it can be seen that the control 9 of the machine tool 2 is positioned in the foot part 6 of the machine tool 2 . The controller 9 of the machine tool 2 is used to control and regulate various processes in relation to the machine tool 2 and in relation to the accumulator 3. The controller 9 controls in particular the current or the amperage from the accumulator 3 to the machine tool 2 and in particular flows to drive the drive 8 designed as an electric motor.

Die Steuerung 9 der Werkzeugmaschine 2 enthält dabei einen Mikrocontroller 18 (auch als MCU bezeichnet) sowie eine Datenschnittstelle 19 mit einem ersten Transceiver 20 als Bestandteil eines Kommunikationssystems für eine differentielle Kommunikation zwischen dem Akkumulator 3 und der Werkzeugmaschine 2. Die Datenschnittstelle 19 der Werkzeugmaschine 2 ist dabei eine von insgesamt zwei Datenschnittstellen zu dem Kommunikationssystem für die differentielle Kommunikation zwischen dem Akkumulator 3 und der Werkzeugmaschine 2. Wie nachfolgend noch beschreiben ist enthält der Akkumulator 3 die andere der beiden Datenschnittstelle 29.The controller 9 of the machine tool 2 contains a microcontroller 18 (also referred to as an MCU) and a data interface 19 with a first transceiver 20 as part of a communication system for differential communication between the accumulator 3 and the machine tool 2. The data interface 19 of the machine tool 2 is one of a total of two data interfaces to the communication system for the differential communication between the accumulator 3 and the machine tool 2. As will be described below, the accumulator 3 contains the other of the two data interfaces 29.

Der Akkumulator 3 enthält im Wesentlichen ein Gehäuse 21 mit einer Akku-Schnittstelle 22. In dem Gehäuse 21 des Akkumulators 3 sind eine Vielzahl an Energiespeicherzellen 23 sowie eine Steuerungselektronik 24 mit einem Mikrocontroller 25 und einem Aufweckschaltkreis 26 (auch als Wake-Up-Circuit bezeichnet) enthalten. Der Aufweckschaltkreis 26 dient zum Einstellen der Steuerungselektronik 24 von einem Deaktivierungsmodus in einen Aktivierungsmodus. Mit anderen Worten: der Aufweckschaltkreis 26 weckt die Steuerungselektronik 24 wieder auf, nachdem diese eingeschlafen ist.The rechargeable battery 3 essentially contains a housing 21 with a rechargeable battery interface 22. In the housing 21 of the rechargeable battery 3 there are a large number of energy storage cells 23 and control electronics 24 with a microcontroller 25 and a wake-up circuit 26 (also referred to as a wake-up circuit ) contain. The wake-up circuit 26 serves to set the control electronics 24 from a deactivation mode to an activation mode. In other words, the wake-up circuit 26 wakes up the control electronics 24 after they have gone to sleep.

Der Akkumulator 3 enthält des Weiteren eine Datenschnittstelle 29 mit einem zweiten Transceiver 30 als Bestandteil eines Kommunikationssystems für eine differentielle Kommunikation zwischen dem Akkumulator 3 und der Werkzeugmaschine 2.The accumulator 3 also contains a data interface 29 with a second transceiver 30 as part of a communication system for differential communication between the accumulator 3 and the machine tool 2.

Die Temperaturüberwachung des Akkumulators 3 erfolgt mittels eines nicht gezeigten Heißleiters (auch NTC-Widerstand oder NTC-Thermistor genannt), der in dem Akkumulator 3 positioniert ist. Die Energiespeicherzellen 23 können auch als Akku-Zellen bezeichnet werden und dienen zum Aufnehmen, Speichern und Bereitstellen einer elektrischen Energie bzw. einer elektrischen Spannung.The temperature of the accumulator 3 is monitored by means of a non-illustrated thermistor (also called an NTC resistor or NTC thermistor), which is positioned in the accumulator 3 . The energy storage cells 23 can also be referred to as rechargeable battery cells and are used to receive, store and provide electrical energy or an electrical voltage.

Die Akku-Schnittstelle 22 ist an einer Seite des Gehäuses 21 positioniert. Die Akku-Schnittstelle 22 enthält eine Anzahl an Stromsteckern 27 zum Aufnehmen und Abgeben von elektrischem Strom sowie Datensteckern 28 zum Senden und Empfangen von Signalen zwischen der Werkzeugmaschine 2 und dem Akkumulator 3. Über die Stromstecker 27 kann der elektrische Strom von den Energiespeicherzellen 23 abgegeben werden.The battery interface 22 is positioned on a side of the case 21 . The battery interface 22 contains a number of power plugs 27 for receiving and delivering electrical power and data plugs 28 for sending and receiving signals between the machine tool 2 and the accumulator 3. The electrical power can be released from the energy storage cells 23 via the power plugs 27 .

Wie in Figur 1 und 2 gezeigt, sind die Stromstecker 27 des Akkumulators 3 mit den Stromanschlüssen 16 der Werkzeugmaschine 2 verbunden. Ebenso sind die Datenstecker 28 des Akkumulators 3 mit den Datenanschlüssen 17 der Werkzeugmaschine 2 verbunden.As in figure 1 and 2 shown, the power plugs 27 of the accumulator 3 are connected to the power connections 16 of the machine tool 2 . The data plugs 28 of the accumulator 3 are also connected to the data connections 17 of the machine tool 2 .

Durch die Verbindung kann elektrischer Strom von den Energiespeicherzellen 23 des Akkumulators 3 zu der Werkzeugmaschine 2 fließen. Des Weiteren können Signale zur Kommunikation zwischen dem Akkumulator 3 und der Werkzeugmaschine 2 ausgetauscht werden.Electric current can flow from the energy storage cells 23 of the accumulator 3 to the machine tool 2 through the connection. Furthermore, signals for communication between the accumulator 3 and the machine tool 2 can be exchanged.

Wie der Figur 1 zu entnehmen ist, ist der Aktivierungsschalter 13 an einer 5c Vorderseite des Handgriffs 5 positioniert. Durch ein Bewegen des Aktivierungsschalters 13 in Richtung A kann ein Signal von dem Aktivierungsschalter 13 an die Steuerung 9 gesendet werden, wodurch die Steuerung 9 wiederum ein Signal an die Steuerungselektronik 24 des Akkumulators 3 sendet. Durch das an die Steuerungselektronik 24 gesendete Signal wird elektrische Energie bzw. elektrischer Strom mit einem bestimmten Stromwert von dem Akkumulator 3 für den elektrischen Verbraucher der Werkzeugmaschine 2 und insbesondere den als Elektromotor ausgebildeten Antrieb 8 freigegeben. Die Werkzeugmaschine 2 hat eine (nicht gezeigte) Stromeinrichtung, mit der die Stromstärke des Versorgungstroms gemessen werden kann. Wenn ein Versorgungsstrom mit einer zulässigen Stromstärke gemessen wird, kann der Versorgungsstrom zu den elektrischen Verbrauchern der Werkzeugmaschine 2 fliessen. Alternativ oder zusätzlich kann die Strommesseinrichtung auch in dem Akkumulator 3 positioniert sein.Again figure 1 as can be seen, the activation switch 13 is positioned on a front side 5c of the handle 5 . By moving the activation switch 13 in direction A, a signal can be sent from the activation switch 13 to the controller 9 , as a result of which the controller 9 in turn sends a signal to the control electronics 24 of the accumulator 3 . The signal sent to the control electronics 24 releases electrical energy or electrical current with a specific current value from the accumulator 3 for the electrical consumer of the machine tool 2 and in particular for the drive 8 designed as an electric motor. The machine tool 2 has a current device (not shown) with which the current strength of the supply current can be measured. If a supply current with a permissible current intensity is measured, the supply current can flow to the electrical consumers of the machine tool 2 . Alternatively or additionally, the current measuring device can also be positioned in the accumulator 3 .

Um ein Signal entsprechend der Wegstrecke des Aktivierungsschalters 13 in Richtung A an die Steuerung 9 zu senden, enthält der Aktivierungsschalter 13 ein nicht gezeigtes Potentiometer, auch Poti genannt.In order to send a signal corresponding to the distance traveled by the activation switch 13 in direction A to the controller 9, the activation switch 13 contains a potentiometer (not shown), also called a potentiometer.

Wenn sich der Aktivierungsschalter 13 wieder in Richtung B bewegt, wird ein entsprechendes Signal mit Hilfe des (nicht gezeigten) Potentiometers an die Steuerung 9 gesendet, sodass kein elektrischer Strom mehr vom Akkumulator 3 zu der Werkzeugmaschine 2 fließt.When the activation switch 13 moves in direction B again, a corresponding signal is sent to the controller 9 with the aid of the potentiometer (not shown), so that electric current no longer flows from the accumulator 3 to the machine tool 2 .

Die Kommunikation zwischen dem Akkumulator 3 und der Werkzeugmaschine 2 erfolgt über ein Kommunikationssystem in Form eines CAN-Datenbuses. Zur Teilnahme an dem Kommunikationssystem enthält sowohl der Akkumulator 3 als auch die Werkzeugmaschine 2 jeweils eine Datenschnittstelle 19, 29 mit einem Transceiver 20, 30. Die Transceiver 20, 30 sind dabei als CAN-Transceiver ausgestaltet. Wie in Figur 2 angedeutet ist der Transceiver 20 der Werkzeugmaschine über die Datenschnittstelle und einer ersten Kommunikationsleitung 31 (auch als COM-High- oder CAN-High-Leitung bezeichnet) sowie einer zweiten Kommunikationsleitung 32 (auch als COM-Low- oder CAN-Low-Leitung bezeichnet) und der Datenschnittstelle 29 mit dem Transceiver 30 des Akkumulators 3 verbunden. Wie ebenfalls der Figur 2 zu entnehmen ist, ist der Aufweckschaltkreis 26 des Akkumulators 3 mit der ersten Kommunikationsleitung 31, d.h. COM-High, verbunden. Alternativ kann der Aufweckschaltkreis 26 des Akkumulators 3 mit der zweiten Kommunikationsleitung 32, d.h. COM-Low, verbunden sein.The communication between the accumulator 3 and the machine tool 2 takes place via a communication system in the form of a CAN data bus. To participate in the communication system, both the accumulator 3 and the machine tool 2 each contain a data interface 19, 29 with a transceiver 20, 30. The transceivers 20, 30 are designed as CAN transceivers. As in figure 2 indicated is the transceiver 20 of the machine tool via the data interface and a first communication line 31 (also referred to as COM high or CAN high line) and a second communication line 32 (also referred to as COM low or CAN low line) and the data interface 29 is connected to the transceiver 30 of the accumulator 3. As also the figure 2 can be seen is the wake-up circuit 26 of the accumulator 3 is connected to the first communication line 31, ie COM high. Alternatively, the wake-up circuit 26 of the accumulator 3 can be connected to the second communication line 32, ie COM-Low.

In dem Fall, dass sich die Werkzeugmaschine 2 und der Akkumulator 3 für eine gewisse Zeitdauer, d.h. mindestens 2 Minuten, nicht in Anwendung befindet, wird der Akkumulator 3 mit Hilfe der Steuerungselektronik 24 von einem Aktivierungsmodus automatisch in einen Deaktivierungsmodus versetzt. Wenn sich der Akkumulator 3 in dem Deaktivierungsmodus befindet, fließt kein elektrischer Strom von den Energiespeicherzellen 23 zur Steuerelektronik 24 und zu der Werkzeugmaschine 2. Darüber hinaus sind alle möglichen elektrischen Verbraucher des Akkumulators 3, wie z.B. die Steuerungselektronik 24, der Temperatursensor zur Überwachung der Akku-Temperatur oder dergleichen, ausgeschaltet. Der Deaktivierungsmodus dient zum Stromsparen, da die elektrische Spannung in den Energiespeicherzellen 23 keiner Last ausgesetzt ist.In the event that the machine tool 2 and the accumulator 3 are not in use for a certain period of time, i.e. at least 2 minutes, the accumulator 3 is automatically switched from an activation mode to a deactivation mode with the aid of the control electronics 24 . If the accumulator 3 is in the deactivation mode, no electric current flows from the energy storage cells 23 to the control electronics 24 and to the machine tool 2. In addition, all possible electrical consumers of the accumulator 3, such as the control electronics 24, the temperature sensor for monitoring the accumulator -Temperature or the like, turned off. The deactivation mode is used to save power since the electrical voltage in the energy storage cells 23 is not exposed to any load.

Wenn nach einer bestimmten Zeitdauer die Verwendung der Werkzeugmaschine 2 und des Akkumulators 3 wiederaufgenommen werden soll, muss zunächst der Akkumulator 3 als Energiespender der Werkzeugmaschine 2 von dem Deaktivierungsmodus wieder in den Aktivierungsmodus gebracht werden. Zur erneuten Inbetriebnahme der Werkzeugmaschine 2 wird zunächst der Aktivierungsschalter 13 in Richtung A bewegt. Hierdurch wird ein Signal über die Steuerung 9 der Werkzeugmaschine 2 gesendet. Der Transceiver 20 der Werkzeugmaschine 2 sendet ein Signal (z.B. ein Bit) über die Datenschnittstelle 19, die erste und zweite Kommunikationsleitung 31, 32 an die Datenschnittstelle 29 und den Transceiver 30 des Akkumulators 3.If, after a certain period of time, the use of the machine tool 2 and the accumulator 3 is to be resumed, the accumulator 3 as the energy dispenser of the machine tool 2 must first be switched from the deactivation mode back to the activation mode. To start up the machine tool 2 again, the activation switch 13 is first moved in direction A. As a result, a signal is sent via the controller 9 of the machine tool 2 . The transceiver 20 of the machine tool 2 sends a signal (e.g. a bit) via the data interface 19, the first and second communication lines 31, 32 to the data interface 29 and the transceiver 30 of the accumulator 3.

Zum Senden eines Signals in Form eines Bits über das Kommunikationssystem, wird sowohl die COM-High-Leitung 31 als auch die COM-Low-leitung 32 in einen dominanten Zustand versetzt. Der Aufweckschaltkreis 26 des Akkumulators 3 ist mit der COM-High-Leitung 31 verbunden. Um die Steuerungselektronik 24 des Akkumulators 3 von dem Deaktivierungsmodus wieder in einen Aktivierungsmodus einzustellen, benötigt der Aufweckschaltkreis 26 des Akkumulators 3 eine elektrische Spannung von mindestens 0,9 Volt. Zur Versorgung des Aufweckschaltkreises 26 mit einer ausreichenden elektrischen Spannung wird der Spannungswert von der COM-High-Leitung 31 im dominanten Zustand des als CAN-Datenbuses ausgestalteten Kommunikationssystems von dem Aufweckschaltkreis 26 detektiert. Der Spannungswert der COM-High-Leitung 26 in einem dominanten Zustand beträgt dabei 3,5 Volt, sodass eine ausreichend große Spannung zur Aktivierung des Aufweckschaltkreises 26 zur Verfügung steht. Alternativ ist es auch möglich, dass der Spannungswert mit 1,5 Volt der COM-Low bzw. zweite Kommunikationsleitung 32 zur Versorgung des Aufweckschaltkreises 26 mit einer ausreichenden elektrischen Spannung (d.h. größer als 0,9 Volt) verwendet wird. Der Aufweckschaltkreis 26 ist dafür mit der COM-Low bzw. zweite Kommunikationsleitung 32 verbunden.To send a signal in the form of a bit over the communication system, both the COM high line 31 and the COM low line 32 are placed in a dominant state. The wake-up circuit 26 of the accumulator 3 is connected to the COM high line 31 . In order to set the control electronics 24 of the accumulator 3 from the deactivation mode back into an activation mode, the wake-up circuit 26 of the accumulator 3 requires an electrical voltage of at least 0.9 volts. In order to supply the wake-up circuit 26 with sufficient electrical voltage, the voltage value of the COM high line 31 is detected by the wake-up circuit 26 in the dominant state of the communication system designed as a CAN data bus. The voltage value of the COM high line 26 in a dominant state is 3.5 volts, so that a sufficiently large voltage to activate the wake-up circuit 26 is available. Alternatively, it is also possible that the voltage value of 1.5 volts of the COM low or second communication line 32 to Supply of the wake-up circuit 26 with a sufficient electrical voltage (ie greater than 0.9 volts) is used. For this purpose, the wake-up circuit 26 is connected to the COM low or second communication line 32 .

Der Aufweckschaltkreis 26 stellt nach dem Detektieren des Spannungswerts der COM-High-Leitung bzw. der ersten Kommunikationsleitung 31 im dominanten Zustand die Steuerungselektronik 24 des Akkumulators 3 von dem Deaktivierungsmodus wieder in den Aktivierungsmodus. Entsprechendes gilt, wenn in einer alternativen Ausgestaltungsform der Aufweckschaltkreis 26 mit der COM-Low bzw. zweite Kommunikationsleitung 32 verbunden ist.After detecting the voltage value of the COM high line or the first communication line 31 in the dominant state, the wake-up circuit 26 switches the control electronics 24 of the accumulator 3 from the deactivation mode back to the activation mode. The same applies if, in an alternative embodiment, the wake-up circuit 26 is connected to the COM low or second communication line 32 .

Im Aktivierungsmodus wird zur Versorgung der elektrischen Verbraucher, insbesondere des Elektromotors, ein bestimmter Stromwert von den Energiespeicherzellen 23 des Akkumulators 3 an die Werkzeugmaschine 2 gesendet. Darüber hinaus werden auch wieder alle Überwachungsfunktionen des Akkumulators 3, wie z.B. die Temperaturüberwachung, wiederaufgenommen.In the activation mode, a certain current value is sent from the energy storage cells 23 of the accumulator 3 to the machine tool 2 in order to supply the electrical consumers, in particular the electric motor. In addition, all monitoring functions of accumulator 3, such as temperature monitoring, are resumed.

Alternativ kann zur Aktivierung des Aufweckschaltkreises 26 des Akkumulators 3 auch den Spannungswert der COM-High-Leitung bzw. der ersten Kommunikationsleitung 31 im rezessiven Zustand detektiert werden. Hierbei wird eine Spannung mit 2,5 Volt von der COM-High-Leitung bzw. der ersten Kommunikationsleitung 31 an den Aufweckschaltkreis 26 gesendet. Da zum Aktivieren des Aufweckschaltkreises 22 eine Spannung größer als 0,9 Volt nötig ist, ist auch der Spannungswert der COM-High-Leitung bzw. der ersten Kommunikationsleitung 31 im rezessiven Zustand ausreichend.Alternatively, to activate the wake-up circuit 26 of the accumulator 3, the voltage value of the COM high line or the first communication line 31 can also be detected in the recessive state. Here, a voltage of 2.5 volts is sent from the COM high line or the first communication line 31 to the wake-up circuit 26 . Since a voltage greater than 0.9 volts is required to activate the wake-up circuit 22, the voltage value of the COM high line or the first communication line 31 in the recessive state is also sufficient.

Gemäß einer weiteren Alternative kann zur Aktivierung des Aufweckschaltkreises 26 des Akkumulators 3 auch den Spannungswert der COM-Low-Leitung bzw. der zweiten Kommunikationsleitung 32 im rezessiven Zustand detektiert werden. Auch in diesem Fall ist der Spannungswert größer als 0,9 Volt, nämlich ebenfalls 2,5 Volt.According to a further alternative, to activate the wake-up circuit 26 of the accumulator 3, the voltage value of the COM low line or the second communication line 32 can also be detected in the recessive state. In this case, too, the voltage value is greater than 0.9 volts, namely also 2.5 volts.
